The Simple Antenna Grounding System by K3DAV

The following three photos are of the new grounding system I built. I installed it on April 1, 2012 in preperation for the two new antennas. The first pic shows the box mounted over where the 4 coax lines enter the dwelling. The box is made of a polypropylene material, and the box is called a SockIt-Box.

It is designed to insulate multiple AC outlet extention cord connections in a sealed waterproof box when working near water or outside if it begins to rain.

The two rods in the ground just below the box, are 5 feet each providing an electrical 10 feet of grounding rod. 10 gauge solid copper wire is used to ground the antennas.

This photo shows my work inside the box. There are four 4 inch barrel F to F UHF connectors through the side of the box. A single 10 gauge solid copper wire is looped and held firmly to each barrel with hose clamps, then runs down and outside the box for connection to the ground wire from the ground rods.

The LMR-400 coax lines that run from the radio bench, exit the wall directly into this box and connect to the barrels. When the lid is attached, the contents of the box are sealed from the outside weather year-round. Not even bees and wasps can get in to make their whopper nests. The yellow tape on each wire is to label them from 1 through 4.
